00]? OR BOBBIN HOLDER.

Application filed August 29, 1918. Serial'No. 251,595.

To all whom it may concern: 7

Be it known that I, EDWARD F. PARKS, a

citizen of the United States, residing at Providence, in the county of Providence, State of Rhode Island, have invented certain new and useful Improvements in Cop or Bobbin Holders, of which the following is a specification.

My invention is an improved bobbinor cop-holder for use on winding machines and other textile apparatus. The object of my improvement is to provide means for holding different ty es of cops, bobbins or other yarn-supplies to adapt them for delivering the material to winding, reeling or similar machines while allowing for more convenient application of the bobbins to the holder and greater facility in dofling the exhausted bobbins. To this end my invention consists essentially of a holder or spindle which automatically grips the bobbin placed thereon, While at the same time positioning it in proper relation to the point to which the yarn is to be delivered; and one which is also arranged to assume a more convenient position when the bobbin is withdrawn whereby to facilitate and expedite the application of a new bobbin thereto.

The manner and means for carrying out these improvements are fully described in the following specification, illustrated by the accompanying drawings, in which like reference characters designate. like parts. In the drawings':-

Figure l is aside elevation of my improved cop-holder showing it in position to receive the cop or bobbin;

Fig. 2, a similar view, illustrating the bobbin held in place on the holder in posi-' tion to deliver its yarn; and

Fig. 3, an end View of the cop-spindle showing the method of securing it to its base.

Referring to Figs. 1 and 2, 2 designates a bracket or bearing-member which is adapted to be supported from any convenient part of the winding machine or other apparatus on which the device is used. As here shown the. bracket 2 is formed with a curved arm or lug 3 adapted to be hooked across a horizontal bar or rod 4 which forms a part of or is mounted on the machine frame. A set-screw 5 extending transversely through the end of the lug 3 is provided with a pointed end arranged to impinge against the side of the rod 4 to clamp the bracket 2 in position thereon. opposite side of the bracket 2 is an extension or arm 6 which is cutaway at its center.

or slotted at 7, as shown by the dotted line in Fig. 1, to provide two spaced-apart ears 8. Extending downwardly from the bracket 2 is a fiat plate or finger 9 formed integral with the arm 6 and employed for a purpose as later described.

On the r Hingedly mounted on the bracket 2 is the cop spindle or holder 10 which comprises theseveral parts as next described. The base or butt end of the holder 10 is preferably constructed in the form of a tapered -plug or cone 1]. which is'adapted to fit into the bore at the butt endi'of the bobbin B, see Fig. 2, to center the latter axially therewith. Projecting from the base of the conical plug 11 is a flat-sided tongue 12 which is received in the slot 7, between the ears 8, 8 of the bracket 2, and pivoted thereto by means of a 'cross pin 18. Cut into one side of the plug 11 is a slot 14, see Fig. 3, which extends rearwardly from, its smaller end to a square shoulder 15, and is then continued through its base flush with the side of the tonguev 12, see also Figs. 1 and 2. The squared end of the slot 14:, that is the shoulder 15, is bored with a hole .16 which is located axially of the plug 11. r

Projecting from the end of the plug 11'.

is a ton s-like spring-member or splitspindle 1 which servesas the mandrel or skewer for the cop or bobbin B, see Fig. 2. Preferably this element is constructed of half-round rod, bent back on itself at 18,

see Fig. 1, to form a blunt-pointed tip), and v .hold it in place in the bore 16. The opposite leg 20 of the spindle 17 extends in parallel relation with the end of the main leg 19 for legs 19 and 20 of the spindle or skewer 17 are sprung together, as shown in Fig. 2, their central portions will remain slightly bowed apart, owing to the inherent spring tendency of the steel rod from which they are constructed. This provides that "the skewer 17 will exert a' frictional grip against the sides of the bore 6 of the bobbin B when the latter is placed thereon, thereby serving as a retaining-means to prevent accidental removal. As the sides of the skewer are contracted within the bore b of the bobbin B the angular extension 23 at the end of the leg 19 will slide into place withinthe slot 14in the cone or plug 11, while its straight portion 24 will enter the slot 7 in the bracket 2. When the bobbin B is removed from the skewer 17 the leg 19 is released and springs back to engage the end of its extension 24 with the vertical finger 9 on the bracket 2,- whereby it acts as a catch or detent to hold the spindle in elevated position as illustrated in Fig. 1.

The method of operation of the complete device is as follows: My improved copholder is intended particularly for suspending the cop or bobbin in vertical, inverted position to adapt it to deliver its supply of yarn to a point below.- For this purpose the bracket 2 .is attached to an overhead bar. or rod 4 by hooking its lug 3 thereover and binding the set-screw 5 thereagainst. Fig. 1 illustrates the cop-spindle or skewer 17 in raised'position with the end 24 of its expanding leg 20 bearing against the finger 9 on the bracket 2 to hold it at a convenient angle to provide for placing the bobbin or cop thereon. The skewer 17 is adapted to receive cops or pirns wound on paper tubes, or any usual type of bobbin such as shown in Fig. 2, the latter being wound on the wooden core or holder B. The bobbin Bis applied to the skewer 17 by forcing it on to the pointed tip 18, and the spring-leg 20 will thereby be caused to contract against the leg 19 as the skewer enters the bore 6 of the bobbin. The bobbin B is pushed onto bore of the tube or bobbin serves to center the latter axially on the spindle. As the two legs of the skewer 17 are brought together under the compression of the bobbin B their natural spring tendency causes them to be bowed outwardly slightly at the center to frictionally grip the interior of the bore 6, as prev1ously explained, and in this manner the cop or bobbin is held securely in place to prevent accidental removal.

The contraction of the leg 20 of the skewer l7 releases its end from the finger 9 on the bracket 2 and causes it to be entered in the slot 14 in the plug 11. I Now, as soon as the operator releases the bobbin the holder 10 will swing downwardly on its pivot 13, under the influence of gravity,- and the bobbin will assume a vertical position as shown in Fig. 2. In this way the cop-holder is automatically returned to its operative position immediately the bobbin is placed thereon, without the necessity of releasing its catch or detent.

When the supply of yarn is exhausted the empty bobbin is removed or defied from the holder by a single motion of the hand.- The operator simply grasps the tube or empty bobbin B and pulls it outwardly away from the bracket 2. This action causes the skewer or spindle 17 to be swung upwardly toward the horizontal, and as the bobbin is drawn off therefrom its. leg 20 will spring back to the position shown .in Fig. 1 to engage its the spring-leg 20 is retracted again to carry its end into the slot 14 in'the plug 11, and

the holder 10 is then free to drop into ver tical position as shown in Fig. 2. In this manner the device operates automatically to hold the cop-spindle raised to receive the bobbin and to return to operative position as soon as the bobbin is in place.

My improved device is designed particularly for use on machines where space is limited or when it is required to place-the yarn-supply in close relation to the point to which the yarn delivers. It is often impracticable to place the bobbin at sufficient distance from the operating parts of the machine to allow for its removal from its spindle in line therewith. In such cases, by employing the present, improved device the bobbin may be drawn off at the side to clear any obstructions which might prevent it withdrawal in another direction. At the same time this arrangement for swinging the bobbin-holder to the side provides for greater convenience in withdrawin the bobbin toward the operator and clearm it from the machine below. A further 1mproved feature of the device is the automatic operation of the detent-means which acts upon the removal of the bobbin to hold the spindle in raised position, and immediately upon the application of a new bobbin releases it to allow it to return to its operative position. It will be observed that the bobbin-holder cannot remain out of its delivery position as long as a bobbin is in place on the spindle, but must return thereto after being drawn aside for any purpose. That is to say, the operator may draw the bobbin to one side or raise it for the sake of convenience in piecing up a broken yarn, but upon its release it will automatically return to its position of delivery. When, however, the bobbin is dofied, the cop-holder remains in its raised position to facilitate the application of a fresh bobbin to the spindle, and in this way considerable time and energy is saved on the part of the operator andthe whole operation of the machine is expedited.

My improved device is extremely simple in construction, economical to manufacture and proof against derangement or getting out of order. It may be used to advantage on various and sundry types of textile apparatus and is universally adaptable to practically all forms of cops or bobbins. Various modifications might be made in the construction and arrangement of the parts of the device without departing from the spirit or scope of the invention; therefore, without limiting myself to the exact embodiment herein shown and described, what I claim is 1. The combination with a tilting bobbinholder, of means for engaging the bobbin to secure it in place on the holder, said means adapted to maintain the holder in its tilted position when the bobbin is removed therefrom and to release the holder to allow it to return to normal position when another bobbin is placed thereon.
